ROAD-OILING MACHINE.

SPECIFICATION forming part of LettersPatent No. 703,327, dated June 24, 1902.

Application filed SeptemherlZ, 1901. Serial No- 75,187. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE F. WHITE, a citizen of the United States, and a resident of Chino, in the county of San Bernardino and State of California, have invented a new and Improved Road-oiling Machine, of which the following is a full, clear, and exact description.

The invention relates to machines used in making and preserving roads, paths, &c.

The object of the invention is to provide a new and improved road-oiling machine which is simple and durable in construction and arranged to conveniently and regularly distribute the petroleum over the whole surface to be oiled, to gage the amount distributed, and to allow of discharging difierent quantities of petroleum on different portions of the width of the road, according to the condition and requirements of the road-surface.

.The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out-in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a rear end elevation of the improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of the improvement with parts broken out and the vehicle omitted, and Fig. 4 is an enlarged transverse section of the distributing-pipe and its gage.- The road-oiling machine preferably forms part of an oil-tank wagon or other vehicle A, supporting a storage tank or reservoir 13 for containing a large quantity of crude petroleum or similar liquid. This tank 13 is pro vided with an outlet-pipe 0, having a valve 0 under the control of the operator, the pipe opening into a distributing box or tank D, secured toa pivot E, mounted to turn in suitable brackets E, attached to the frame of the vehicle A. From the bottom of the dist-ributing box or tank D lead the connecting-pipes F, opening into the ends of a distributingpipe G, extending transversely and having openings G at or near the bottom thereof and spaced suitable distances apart to distribute the petroleum over the road-surface.

The pipes G andv F are hung on a suitable framework H, secured to the pivot E and supporting a transverse rod'H, connected with one end of a chain 1, extending upwardly and winding on a shaft 1, journaled in suitable bearings carried by the vehicle-frames On the shaft 1 is held a crank-arm'l under the control of the operator for turning the shaft 1 to wind up or unwind the chain I to swing the frame H, and with it thepipes F G and the distributing-box D, upward or downward into an active or inactive position. A ratchetwheel I issecured on the shaft 1 and is engaged by a pawl I to lock the said ratchet-wheel and the shaft 1 in either of their two positions-that is, when the pipes F G and the box D are in a raised 'or a lowermost position. The pipes F are provided with gate-valves F, having their stems F connected by links F with levers F fulcrumed on theframe Hand independently under the control of the operator, so that either or both valves F can be opened or closed, as desired. The distributing-pipe G is preferably plugged at or near the middle thereof, as indicated in Fig. 3, so that either or both sides of the said'distributingspipe G can be filled with petroleum by opening the valves F. One, of the lovers F is conheated with its link F above the levers fulcrum, and the other is connected with its link below the fulcrum, so that the operator grasping both levers and moving the same to the right or left simultaneously opens or. closes both valves F. The distrib- ;uting-pipe G is provided on opposite sides of its middle orplugged portion with gages J, each having a plurality of openings J, somesections of each gage are provided with clamping-arms J engaged by clamping-screws J 3 to securely hold or clamp each gage J on the distributing-pipe G after the gage shall have been adjusted axially on the distributingpipe and set to allow a desired amount of petroleum to flow through the registering openings G J. The rod H,previously mentioned, is pivotally connected by braces H with the pivot E, and the said rod H is adapted to rest on the bottoms of slots H formed in depending arms H secured to the frame of the wagon or vehicle A, so that when the frame II and parts carried thereby are in lowermost position it is securely held against further downward movement by the arms H The operation is as follows: When the device is in use, the several parts are in a lowermost position, as illustrated in the drawings, and the distributing box or tank D is filled with petroleum from the storage-tank B by the operator opening the valve 0. As the vehicle is drawn over the road the operator open either or both valves F, so as to allow the petroleum to flow from the distributing-box D, by way of the pipes F, into the distributing-pipe G, from which passes the petroleum in thin streams through the registering openings G J onto the road-bed. It is understood that while the vehicle is in motion the operator watches the filling of the box D with oil from the storage-tank B, so that the said box D does not overflow. In case there is a tendency to overflowing the operator shuts down on the valve 0 to regulate the amount fiowing from the tank B into the box D. When the end of the road or the end of the section to be oiled is reached, the valves F on the connecting-pipes F are closed by the operator maniputating both levers F at the same time, and then the valve C is closed.

Should it be desired to put on a strip of oil one-half the width of the machine, as often happens in going overa road the second time to retouch the loose places, then one of the levers F only is used for opening the valve F on the corresponding side. Should it be desired to put on a strip of oil less than half the width of the machine, then all the gages J, with the exception of one, are closed. Should it be desired to put on a strip of oil more than half the width of the machine, then one gage J only is closed and the remaining ones left open. In case it is desired to put on different quantities of oil on different sections of the width of the machine, as is sometimes required on a road which is looser in some parts of its width than in other parts, then the gages J are set differently one from the other, so as to allow more oil to pass out of one portion of the distributing-pipe G than of another. In case the machine is moved about from place to place-then the operator turns the crank-arm 1 so as to wind up the chain on the shaft I, and thereby raise the working parts to clear obstacles which may be in the road.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a road-oiling machine, the combination with a storage-tank, of suitable hangers, a frame suspended by said hangers, adistributing-tank carried by the frame and in communication with the storage-tank, a distributing-pipe connected with the distributing-tank and supported on the frame, and means for vertically adjusting the frame and the devices thereon.

2. In a road-oiling 1nachine, the combination with a tank, of front hangers, rear hangers having suitable guideways, a frame pivoted to the front hangers and confined in the guideways of the rear hangers, a distributingpipe carried by the frame and having communication with the tank, and means for adj usting said frame and the devices supported thereon.

3. In a road-oiling machine, the combination with a suspended frame, and an elevated tank, of a perforated distributing-pipe carried by the frame and having a plug, connecting-pipes leading from the tank and communicating with the ends of the distributingpipe, controlling-valves fitted in the connecting-pipes, levers independently mounted on the frame at points between the valves and disposed in close relation for simultaneous operation, and individual connections between the levers and the valves.

5. A road-oiling machine, having a distributing-pipe provided with discharge-openings and slotted gages arranged longitudinally on said distributing-pipe and adjustable axially thereon to change the relation of the slots in the gages to the openings in the distributingpipe, and gages being adjustable independently one of the other.

6. A road-oiling machine, having a distributing-pipe provided with discharge-openings, slotted gages arranged longitudinally on said distributing pipe and adjustable axially thereon, the gages being adjustable independent one of the other, and means for clamping the gages circumferentially around the distributing-pipe.
